This driver does no transformation of the gallium calls
going to the real driver, like the identity matrix. It is
intended to be the basis for transforming and/or debug
drivers like trace and rbug.
Authors of this patch are:
Michal Krol, orignal heavy lifting.
José Fonesca, object wrapping code stolen from trace.
Jakob Bornecrantz, put it all toghether and renamed a stuff.
This is somewhat nasty, but we need to do Y-tiled depth for FBO support.
May help with corruption and hangs since enabling texture tiling, and
since switching depth textures to Y tiled.
Fixes piglit depthtex.c on 965.
The reshape() function was called when there was no GLX context so
the viewport/modelview/projection setup wasn't doing anything. Move
the call to reshape() into draw().
Also, remove -stereo, -fullscreen options and do some general clean-up.
The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.
glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

We currently don't have support for SGI_swap_control for direct
contexts with DRI2, so disable reporting the extension. Reporting
the extension, and then having glXSwapIntervalSGI() "succeed"
but do nothing can confuse applications.

Be clearer that this is the number of generic vertex program/shader
attributes, not counting the legacy attributes (pos, normal, color, etc).
(cherry picked from commit 4a95185c9f)
Call the _mesa_set_enable() functions instead of driver functions, etc.
Also, add missing code for 1D/2D texture arrays.
(cherry picked from commit aac19609bf)
If we're running a vertex program to emulated fixed-function, we still need
to treat vertex arrays/attributes as if we're in fixed-function mode.
This should probably be back-ported to Mesa 7.5 after a bit more testing.
(cherry picked from commit dda82137d2)
When a GLSL sampler reads from an incomplete texture it should
return (0,0,0,1). Instead of jumping through hoops in all the drivers
to make this happen, just create/install a fallback texture with those
texel values.
Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some
GPU lockups when trying to sample from missing surfaces. If a binding
table entry is NULL, it seems that sampling sometimes works, but not
always (lockup).
Todo: create a fallback texture for each type of texture target?
(cherry picked from commit 3f25219c7b)
This fixes a regression in region read performance that came in with the
texture tiling changes. Ideally we'd have an access flag coming in so we
could also use bo_map_gtt for writing, like we do for buffer objects.
Bug #22190
The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.

I was rather confused when mesa_print_display_list didn't show any of
my glBegin()..glEnd(). Nothing but print_list appears to call
this function, so matching its behavior seems like a good idea.
pbo might be system buffer based or attached to another region. Call
intel_bufferobj_buffer to make sure pbo has a buffer of its own.

intel_bufferobj_subdata is called to migrate data from sys_buffer, and
it expects only one of buffer or sys_buffer is non-NULL.
